Paranoia

Paranoia is the suspiciousness or the belief that one is being harassed, persecuted, or unfairly treated.[1] These feelings can range from subtle and ignorable to intense and overwhelming enough to trigger panic attacks and feelings of impending doom. Paranoia also frequently leads to excessively secretive and overcautious behavior which stems from the perceived ideation of one or more scenarios, some of which commonly include: fear of surveillance, imprisonment, conspiracies, plots against an individual, betrayal, and being caught. This effect can be the result of real evidence, but is often based on assumption and false pretense.
